  • $ 1,80000


Group of exceptionally bright, silvery metallic modified cubic galena with isolated groups of brassy pyrite and iridescent chalcopyrite. The mound-like clusters of pyrite and chalcopyrite on galena are a new combination from the Borieva Mine found late in 2013 from advance mining in new workings. This type of combination is new to me and also to my contact in the district. Undamaged and the best piece I acquired from the lot.
